当前,我国城市轨道交通处于快速发展阶段,并继续保持增长态势,但也面临建设成本不断增加、能源消耗和碳减排压力与日俱增等现实问题。深圳地铁6号线在建设中倡导绿色低碳新理念,以可持续发展为目标,通过综合选线、综合减振降噪、预制装配式和预留预埋等技术创新性应用,其建设成本大幅低于同期建设其它线路,提升了工程建设品质,实现了城市轨道交通绿色建造;同时,通过应用分布式光伏发电、海绵城市、云平台、再生制动能量吸收、牵引网组合开关柜及空气品质提升等技术,大幅降低了运营期能耗,实现了城市轨道交通低碳运营。深圳地铁6号线从设计出发对建设、运营期进行的诸多探索和实践,为城市轨道交通加快绿色低碳转型、挖掘节能减排潜力,实现“碳达峰、碳中和”目标提供了借鉴。

[Abstract]
The urban rail transit in China has been developing rapidly and the growing trend is expected to continue. Meanwhile, practical problems of the increasing construction costs, incremental pressure from energy consumption and carbon emission reduction are nonnegligible. Bearing the goal of sustainable development, Shenzhen Metro Line 6 advocates the new concept of green and low-carbon construction, through the innovative application of technologies not limited to comprehensive route selection, integrated vibration and noise reduction, prefabrication and pre embedding. Its construction cost is significantly lower than that of the other metro lines constructed in the same period, improving the quality of engineering and realizing green construction of urban rail transit. Moreover, the application of distributed photovoltaic power generation, sponge city, cloud platform, regenerative braking energy absorption, combined switch cabinet of traction network and air quality improvement has greatly contributed to the reduction of energy consumption during operation and the achievement of low-carbon urban rail transit operation. The exploration and implementation of Shenzhen Metro Line 6 from design to construction and operation set a convincing illustration of achieving the “peak carbon dioxide emissions and carbon neutrality” goal, accelerating the green and low-carbon transformation of urban rail transit and mining the potential of energy conservation and emission reduction.
